for almost half the price, the logitech has great sound, higher power output, Dolby Pro Logic II, Dolby Digital, DTS decoder (you have to buy your own decoder if you want this functionality), 1 x SPDIF input (TOS Link), 1 x SPDIF input (RCA phono). Yes, it has all the sound decoding so it acts like a mini reciever, with 3 input sets. Analog, Digital Coax, Digital optical, which gives it a lot of value imo... especially later if you want to throw a DVD player into it. If you want to do the same for the Klipsch, which only have analog audio input, you would have to purchase a decoder/reciever, in which case you'll be back here again asking what kinda reciever to get for a Klipsh 4.1/5.1/6.1 multimedia setup

That would seem really sad imo.
sorry, but for a small multimedia system, it was an obvious choice. I was thinking about the Klipsch pro media's, but it was just too high priced for what you get. The sound was slightly better, but the logitech system had a better subwoofer imo.
Honestly, the logitech was perfect for my room. it was also cost efficient. when i play xbox on the 20", the digital audio goes straight into the speakers, so i didn't have to pay for a dolby digital decoder. Same with movies. And all with my computer off.
The quality of your sound connected to your computer is retarded anyways unless you have a near silent PC. and that's not even saying the logitech system sounds bad... it's THX certified and sounds wonderful too.
I have an ONIX RS750/RSS300/RSC200 setup in the living room, and use Paradigm Studio 80 at my santa monica apt, so it's not like i haven't heard better. But for a system used in a bedroom or office, I would recommend the logitech system as opposed to the Klipsch because of price/performance... The klipsch is a big loser in that department.
